My excavator, ("VOTE" Brand), has the pull start cord assy removed and a piece of duct going tight to the side panel, drawing fresh air by the engine flywheel fan/impeller allowing for positive air flow into and out of the engine compartment. Thanks for making this video. Good luck to you!
Several commenters, here, seem to believe the fans are 12" fans. They are 7 inch fans. I have almost the same machine, and a 12" fan would never fit in those areas. I can guarantee that those are 7 inch fans. I hope this is helpful information.
Just wanted to say "THANK YOU" as I did this to mine as well with fusible (15a) inline link. Also added aluminum heat shielding around the exhaust, gas tank, and full sheet under the seat. Changed all new American zerks also. Works Great.
Amazon sells a 200 watt flexible solar panel (100 watt at harborfreight) for $80 that could either keep the battery charged or power another fan, and the panel fits perfectly on top of the sun canopy.
just posted a video to my channel of me testing one of these mini excavators with a TMK 150 tree sheer. I was mind blown how well it handled 5-6" diameter trees!
Frank. You are right. With most cooling systems on almost everything, the goal is to extract or pull the heat from the area. But any air movement I'm sure is a definite upgrade.
@@jaybrown651 Nah. With an air cooled engine, you want to get cold high velocity air to the engine, sucking out the warm air is way less effective and recirculates a lot of cold air. Ever tried to inhale the air over a hot beverage to cool it down? Nah, because it doesn't work. Same thing with a hair dryer. You can blow a piece of paper around from 6ft away with the high velocity air, but if you try to suck anything from more than a few inches, you're out of luck.
I'm curious if your battery is holding up? I believe the charging circuit is only 10 amp on that engine, and the fans draw about 6.7 amps each, so theoretically running both would drain the battery over time.
Would it not work better with one fan pulling and the other pushing to create a flow rather than two fans pushing against each other and negating flow? The fact that you removed the back panel shows that this does not work as well as hoped. Since they are bi-directional fans it would be an easy experiment.
I'd say the grate on the back of the cover has enough holes that the fans aren't really going to be fighting each other. If these two fans were covering the only grates in the machine, one puller and one pusher would certainly be better. In this case, it probably doesn't matter and it'll prevent the fans themselves from being completely heat soaked.
Thanks to our environmental extremists, the Briggs and Stratton is the only motor to pass emissions unless you want to get the Kubota diesel which doubles the price.
@@dalethornton1113 I kept contacting different eBay sellers that indicated the Vietnam engine Kopu KD192F engine in their listing description, but when asked about the engine they all edited their auctions to show it was a B&S. So the EPA change must have just occurred. Sucks damn it. I'm waiting for a delivery on one from the AGT sellers in Chicago. Watched many videos here that had only positive things give the cost. Only negatives I found were from dealers that were pushing their branded product.
Yes most US buyers are now getting the Briggs gas engine, cuz the Koop or ChangChai 1-cyl Diesels are not EPA- or CARB-compliant. In the latter case, the main flywheel fan is ducted to the outside to bring in cool air. Most of the makers have not bothered doing this with the gas engines. I did for mine when I bought it 5y ago from China and installed my own gas engine. If you use an internet search engine, you will find pix of how I did it. Utube is great for vids (see mine for the XN08), but does not allow commenters to respond with pix. The automotive electric fans do move a lot of air, but some of the gas engines, like my Duromax 420, do not put out enough current to power them. The B&S alternator puts out more current.
